Etz Hayim, Sha'ar Kitzur Abeya, Lesson 3

Etz Hayim 150, Chapter 3a. The Yetzer HaTov and the Yetzer HaRa. Are the good and bad inclinations within human beings mere psychological orientations or are they actual external entities of angelic and demonic origins?
This lesson begins with an explanation of what is a life form, what is a soul, what is sentience, what is consciousness, and what is enlightenment. In this context, we can then address the reality of the existence of the angels and demons that cling to us as the two yetzers.
The fall of Adam, the fall of the Da'at and the creation of the Glittering Shell, the Klipah Nogah.
The relationship of the Gevurot forces and the Hasadim forces, how they are supposed to be, and how they are in actuality. How the blemishes in the human soul create imbalance.
The three stages of sefirotic brains (Mohin), ibbur, yenika, and gadlut, and how these correspond to growing levels of consciousness in the growing human soul, from birth through childhood.
